  The base plate 8 has two side webs 12 and 13 that are parallel to each other, and these side webs 12 and 13 provide a guide for the holding plate 18 that will be described in detail below. In this embodiment, since the side web is higher than the flat cable 2, the side web projects beyond the side edge of the incorporated flat cable 2.

  The insulated through contacts 9 are preferably connected to different connectors in order to realize a T-shaped branch in the flat cable 2. These separate connectors are formed in this embodiment as, for example, a direct plug-in compression spring contact 14 that can be contacted particularly quickly and easily (see FIG. 5b), but as a tension spring contact, IDC contact, screw contact, etc. It may be formed or may be formed in another form (not shown).

  The insulating through contact 9 protrudes from the base plate 8 toward the side surface of the flat cable 2 at the tip portions 10 and 11 thereof.

  In accordance with a simple assembly form realized in this case, the insulated through contacts are inserted into the receiving chambers 15 of the base plate 8 together with the direct plug-in contacts 14 respectively. These accommodation chambers 15 are formed open to the side surface of the flat cable 2, whereby the insulating through-contact 9 can be inserted into the accommodation chamber 15 from the side surface side when assembled.

  Another opening is provided on the opposite side of the housing chamber 15 from the flat cable 2, and these openings are branched conductors 17 (see FIG. 2; sometimes combined as a flat cable) and / or branches. An operation tool (opening 16, FIG. 5) for operating the contact can be inserted into the storage chamber 15. In this case, the opening 16 is further configured such that the insulating through contact (particularly the perforated contact) 9 cannot be removed from the receiving chamber 15. In the present embodiment, a plurality of spaces 33 are provided on the side of the base plate 8 opposite to the flat cable 2 for the branch conducting wire 17.

  Since the accommodating chamber 15 and the insulated through contacts for different conductors of the flat cable 2 to be contact-connected may be arranged slightly shifted from each other in the direction of the longitudinal extension of the flat contact 2. The individual IDC contacts may be slightly wider than the conductor spacing of the flat cable 2. In this way, in this embodiment, for example, 11 perforated contacts 9 are accommodated in a narrow space.

  In order to prevent the insulating through contact 9 from falling out of the storage chamber 15, the storage chamber 15 is covered with a holding plate 18 that is engaged from above. The holding plate 18 may have first locking means (locking web 19 in the present embodiment), and the first locking means corresponds to the corresponding second locking means (main book) of the base plate. In the embodiment, it can be locked together with the locking notch 20).

  The holding plate 18 is provided with a plurality of openings, in particular slits 21, from which the insulating through contacts protrude toward the flat cable 2 to be incorporated.

  In the present embodiment, an arbitrary mounting plate 22 for mounting a flat cable can be mounted on the holding plate 18, and this mounting plate 22 is advantageously the contour of the cover of the flat cable to be contact-connected. The flat cable is well positioned and centered in the contour 23, which is advantageous for a reliable contact connection.

  In this embodiment, the mounting plate 22 also has first locking means (locking web 24 in this embodiment), and this first locking means is the engagement in the locking means of the corresponding base plate 8. It can be stopped.

  Furthermore, the mounting plate 22 is also provided with a plurality of openings, particularly slits, through which the insulated through-contacts 9 in a contact connection state protrude from the openings.

  In a state where the contact connection is not established, the mounting plate 22 is still mounted on the base plate 8 at a height at which the insulating through contact 9 does not protrude from the mounting plate 22, so that a flat cable can be mounted. The mounting plate 22 is slidable toward the base plate 8 for a contact connection perpendicular to the flat cable.

  The holding plate 18 and the mounting plate 22 may be integrally formed (not shown).

  For contact connection, the flat cable 2 is first fitted into the mounting plate 22 of the base section of the casing, which has been assembled in advance, so that the flat cable 2 is securely centered and the double tip 10 of the insulated through contact 9 is secured. , 11 (Fig. 2; Fig. 5).

  The original contact connection of the flat cable is then made by the cover section 7. This cover section 7 also serves as an operating unit and is guided so as to be slidable relative to the base section.

  The operation unit includes a support plate 27 that can be placed on a base section to which the flat cable 2 is attached, and a slide cover 28.

  The support plate 27 has a predetermined contour (side web 29 in this embodiment), which cooperates with the contour of the base section (especially the side webs 12 and 13). 27 is assembled, and is movable in the direction perpendicular to the flat cable 2 toward the insulated through contact 9 before connection, but does not move in a direction parallel to the extending portion of the flat cable 2. Or try not to exercise.

  Importantly, at least one or preferably a plurality of wedge-shaped structures 30, 36, 37 with wedge-shaped members or wedge-shaped contours are formed between the slide cover 28 and the support plate 27. .

  The wedge-shaped members 32 and 34 of the first wedge-shaped structure 30 are configured such that when the slide cover 28 is fitted on the base plate in parallel with the flat cable 2, the slide cover 28 attaches the support plate 27, the flat cable 2 and the mounting plate 22. Together with the flat cable 2 and pressed against the insulating through contact 9 in the vertical direction. This gives rise to the fact that the insulated through-contact 9 first contacts the connection plate 22 after penetrating / piercing the mounting plate 22 and then the cable cover 4 and the conductor insulation.

  In this case, the wedge-shaped members 32 and 34 are in contact with the lower part of the slide cover 28 (FIG. 6).

  The wedge-shaped members 32 and 34 may have a constant inclination angle α with respect to the flat cable 2. However, this inclination angle or wedge angle α may be configured to be variable in the longitudinal direction of the flat cable 2 (not shown).

  That is, instead of a theoretically flat wedge, a wedge having a curved upper surface may be used.

  What is important is that the support plate 27 and the insulated through-contact 9 are brought close to each other when the slide cover 28 is slid by the wedge-shaped members 32 and 34, whereby the insulated through-contact 9 is contact-connected to the flat cable 2. is there.

  In addition, at least one web 35 extending perpendicularly to the flat cable 2 is formed on the support plate 27, and the web 35 is rotated further by a screwdriver after contact connection (FIG. 7). The slide cover 28 and the flat cable 2 are tightened so that the flat cable 2 is securely tightened between the support plate 27 and the base section 6 of the casing 5 in a tension-reducing manner.

  In order to operate the tension relief device, another wedge-shaped structure 36, 37 is provided on the inside of the slide cover 28 with one wedge surface each, along the inside of the slide cover 28, the web. 35 slides. In this case, the wedge-shaped structures 30, 36, 37 are adjusted to each other such that tension relief is only activated after the flat band cable is routed.

  The wiring process is shown in FIGS. 2 to 4 and FIGS. The wiring is preferably performed using a screwdriver. This screwdriver can be inserted into the notch 36 of the slide cover 28 and its tip can be supported by the base plate (see FIG. 8). The flat cable 2 can be wired by the swiveling motion. In this case, in order to form a branch in the continuous flat cable 2, it is only necessary to connect the branch conductor 17.
